Nitrogen:
Hi my name is Nitrogen and I am a gas. I am found in the Earth's atmosphere and i make up about 78% of the air. I am sometimes used to preseve historical documents such as the Declaration of Independence. I sometimes like to save lives and i am into the airbags in cars. I also can be a little dangerous and be put into dynamite and other explosive equipment.
Krypton:
Hola! I am Krypton and I am a noble gas. I only make up about 0.00014 percent of the atmosphere. I was discovered by liquifying air! I am never found in my solid forms and I can be used in lightbulbs. I am shot around using lasers.
In the chemistry unit;
~ I would like to do a lot of labs.
~I would like to do more labs with fire and chemicals.
~I would like to learn how to make a liquid turn a different color.

Renewable Resources:
Solar-Used on calculators
Water-produces hydroelectricity
Wind-makes electricity
Geothermal-used in steam genorators
Biomass-uses corn and other crops to make ethanol
Non-renewable Resources:
Nuclear- comes from uranium
Fossil Fuels~
Natural Gas-low output of carbon dioxide
Petroleum-makes synthetic fabric(rayon)
Coal-Most coal used for electric power

~Energy is the ability to do work.
~Work is the action that results if a force causes an object to move in the direction of the force.
~Both energy and work are measured in joules (J)
~One joule is a newton meter.
~The two main types of energy are Kinetic and Potential energy.
~Kinetic energy is the energy of motion.
~Potential energy (stored energy) is the energy an object has because of its position and shape.
~The various forms of energy are thermal, chemical, electrical, sound, light and nuclear energy.
Forms ~Potential energy:~Kinetic Energy:
-chemical energy -Thermal energy
-gravitational energy -Sound Energy
-Electrical Energy
-Light Energy
-Nuclear Energy
